2.2 Unpacking

Your JUKI-6752 Single Board Computer contains sensitive
electronic components that can be easily damaged by static
electricity.

In this section, we describe the precautions you should take while
unpacking, as well as during installation. It is very important that the
instructions be followed correctly, to avoid static damage, and to
successfully install the board.

The system board should be done on a grounded anti-static mat.
The operator should be wearing an anti-static wristband, grounded
at the same point as the anti-static mat.

Inspect the cardboard carton for obvious damage. Shipping and
handling may cause damage to your board. Be sure there are no
shipping and handing damages on the board before processing.

After opening the cardboard carton, exact the system board and
place it only on a grounded anti-static surface component side up.

Again inspect the board for damage. Press down on all the
socketed IC's to make sure that they are properly seated.
Do this only with the board place on a firm flat surface.

Note : DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN

DAMAGED.

You are now ready to install your JUKI-6752 Single Board
Computer.

4.3 BIOS Features Setup

This BIOS Features Setup is designed for customer‘s tuning best
performance of the JUKI-6752 board. As for normal operation
customers don‘t have to change any default setting.
The default setting is pre-set for most reliable operation.

BootUp Sequence :

You could set the sequence of A:,C:,and CDROM.

Video BIOS Shadow C000,32K:

Enable

Shadow C8000-CFFFF,D0000-D7FFF,& D8000-DFFFF :

When the installed add-on card‘s ROM address is as
above address,you could enable the shadow to get higher
operation performance. When you enable the shadow
function,it will also reduce the memory available by between
640KB and 1024KB.

25

- Will increase the video speed.

4.4 Chipset Features Setup

This setup functions are almost working for ChipSet(Intel 430TX).
These options are used to change the ChipSet‘s registers. Please
carefully change any default setting, otherwise the system could be
running un-stable.

Auto Configuration : Enable or Disable

When use the 60nS general type DRAM, please enable the setting
to get the optimal timings.

SDRAM Speculative Read : Enable or Disable

When enable this option, the PCU will send predict commands to
the SDRAM, if a miss happens, the CPU will cancel this command.
Because some OS under certain situations have problem for this
feature, it is normally disable.

26

Memory Hole at 15M-16M : Enable or Disable

This setting reserve 15MB to 16MB memory address space for ISA
expansion cards that specifically require this setting. Memory from
15MB and up will be unavailable to the system because expansion
cards can only access memory up to 16MB.

CPU Warring Temperature : Disable,50

There have a temperature sensor near the CPU, when set the
CPU Warring Tempture to a certain limit which will help customer
secure the system not burn out because of fan failed or other
accident.

Hardware Monitoring :

4.5 Integrated Peripherals

This setup is almost working for Multi-I/O Chip(W83977TF-AW ).
These options are used to change the ChipSet‘s registers. Please
carefully change any default setting to meet your application need
perfectly. The only special concern is Onboard
Serial Port2. If you are using the IrDA port, you have to set this
port accordingly.

4.6 Power Management Setup

Power Management Setup help user handles the JUKI-6752
board‘s “green” function. The features could shut down the video
display and hard disk to save energy for example. The power
management setup screen is as following,

Power Management : Disable, Max Saving, Min Saving,
or User Defined

Max Saving puts the system into power saving mode after a brief
inactivity period. Min Saving is almost the same as Max Saving
except that the inactivity period is longer. User Defined allows you
to set power saving options according to your requirement.

Note : Advanced Power Management(APM

to keep the system time updated when the computer enters
suspend mode activated by the Power Management.
Under DOS environment, you need to add
DEVICE=C:\DOS\POWER.EXE in your CONFIG.SYS

29

) have to be installed

Under Windows 3.x and Windows 95,you have to install Windows
with APM feature. A battery and power cord icon labeled “Power”
Will appear in the “Control Panel”

30

4.7 PNP/PCI Configuration

The PNP/PCI Configuration help user handles the JUKI-6752
board‘s “PCI” function. All PCI bus slots on the system use INTA#,
thus all installed PCI slots must be set to this value..

PNP OS Installed : Yes or No

When PNP OS is installed, interrupts may be reassigned by the OS
when the setting is Yes. When a non-PNP OS is installed or to
prevent reassigning of interrupt settings, select setting to No.

31

Appendix A. Watch-Dog Timer

The WatchDog Timer is a device to ensure that standalone systems can
always recover from abnormal conditions that cause the system to crash.
These conditions may result from an external EMI or a software bug. When
the system stops working, hardware on the board will perform hardware
reset (cold boot) to bring the system back to a known state.

Three I/O ports control the operation of WatchDog Timer.

443 (hex) Write Set WatchDog Time period
443 (hex) Read Enable the refresh the WatchDog Timer.
043/843 (hex) Read Disable the WatchDog Timer.

Prior to enable the WatchDog Timer, user has to set the time-out period.
The resolution of the timer is 1 second and the range of the timer is from 1
sec to 255 sec. You need to send the time-out value to the I/O port – 443H,
and then enable it by reading data from the same I/O port – 443H. This will
activate the timer that will eventually time out and reset the CPU board. To
ensure that this reset condition won’t occur, the WatchDog Timer must be
periodically refreshed by reading the same I/O port 443H. This must be
done within the time-out period that is set by the software, please refer to
the example program. Finally, we have to disable the WatchDog timer by
reading the I/O port -- 843H or 043H. Otherwise the system could reset
unconditionally.

A tolerance of at least 5% must be maintained to avoid unknown routines in the
operating system (DOS), such as disk I/O that can be very time-consuming.
Therefore if the time-out period has been set to 10 seconds, the I/O port 443H
must be read within 7 seconds.

32

Example assembly program:

TIMER_PORT = 443H
TIMER_START = 443H
TIMER_STOP = 843H
